Use C++17 format for nested namespace definitions

Use the new C++17 format for defining nested namespaces in the
phosphor-regulators application.

The definition
  namespace A::B::C
  {
  ...
  }

is now equivalent to
   namespace A
   {
   namespace B
   {
   namespace C
   {
   ...
   }
   }
   }
